Problem

How would you explain a p-value in plain, non-technical language?

Asked in the Onsite stage. Visible fragment of the points-walled onsite section.

Answer this as a practical experimentation question. Explain what a p-value means without relying on formulas first, then connect it to an A/B test. Define the null hypothesis, explain what a small or large p-value indicates, and clarify what a p-value does not prove. Include how you would use it alongside an effect size, confidence interval, pre-specified MDE, and guardrail metrics. State how peeking, multiple comparisons, and sample-ratio mismatch can make a straightforward interpretation misleading.
